Pyrolytic carbon gasification comprehensive transformation utilization system and method for biomass waste resources

Abstract

The invention discloses a pyrolytic carbon gasification comprehensive transformation utilization system and a pyrolytic carbon gasification comprehensive transformation utilization method for biomass waste resources. According to the system, pyrolyzing equipment is connected with a gas supply device through a gas channel of multifunctional heat exchange equipment, and is also connected with carbon powder collection equipment through pneumatic delivery equipment; and a condensed water channel is connected with an afterheat heat supply device through a heat exchanger of the pyrolyzing equipment. The method comprises the following steps that: biomass raw materials are pyrolyzed into a gas mixture containing a combustible gas, a tar gas and an acetic acid gas at high temperature in the pyrolyzing equipment, and carbon is generated; the gas mixture is sucked into the multifunctional heat exchange equipment for heat exchange to separate the combustible gas and the mixed solution of tar and an acetic acid, and water absorbing heat enters heat exchanger of the pyrolyzing equipment for continuous heat exchange to form hot water; and the hot water and the combustible gas are used for centralized gas supply, heating and hot water supply for residents through the gas supply device and the afterheat heat supply device, the acetic acid is used as a foliar fertilizer or a biological bactericide, or is mixed with the carbon to be used as a bio-fertilizer, and the tar is used as an industrial raw material. The comprehensive transformation utilization rate of the biomass waste resources is 100 percent, and the secondary pollution is avoided.

Description

technical field [0001] The invention relates to equipment and methods for utilizing industrial organic solid wastes, agricultural biomass wastes and other waste resources, in particular to a comprehensive transformation and utilization equipment for pyrolysis carbon gasification of biomass waste resources mainly composed of crop straws It is also a comprehensive conversion and utilization device and method for pyrolysis carbon gasification of industrial organic solid waste resources. Background technique [0002] my country is a large agricultural country, and a large amount of biomass resources such as crop stalks and chaff residues are produced in agricultural production and agricultural product processing. Traditional utilization methods are mainly used as household energy, feed, fertilizer, industrial raw materials and construction materials. With the modernization of agricultural technology and the rapid development of the agricultural economy, the rural living sta...

Problems solved by technology

Tar and acetic acid are discharged together with the washing water, which can not be used effectively, but also leads to water source and soil pollution

At the same time as biomass pyrolysis, with the generation of a large amount of heat, the high-temperature combustible gas carrying heat needs to be cooled before it can be used. During the washing and cooling process, the heat is often discharged together with the washing water, which cannot be effectively used and is wasted
